Cow-Calf Producer Interest in Retained Ownership

The beef industry’s share of domestic meat demand continues to decline, as increasing vertical coordination in pork and poultry contribute to these industries’ ability to offer convenient, consistent, and less expensive products. For such vertical coordination to be effective, incentives must be properly aligned so that those responsible for making the most important investments for system profitability are appropriately compensated. This study demonstrates that cow-calf producers who invest in quality registered cattle and those who are interested in incorporating feedlot and carcass data into herd management decisions are also more interested in retained ownership.beef cattle, property rights theory, retained ownership, Livestock Production/Industries, Marketing, Q13,

Association between 5-Year clinical outcome in patients with nonmedically evacuated mild blast traumatic brain injury and clinical measures collected within 7 days postinjury in combat

Importance: Although previous work has examined clinical outcomes in combat-deployed veterans, questions remain regarding how symptoms evolve or resolve following mild blast traumatic brain injury (TBI) treated in theater and their association with long-term outcomes. Objective: To characterize 5-year outcome in patients with nonmedically evacuated blast concussion compared with combat-deployed controls and understand what clinical measures collected acutely in theater are associated with 5-year outcome. Design, Setting, and Participants: A prospective, longitudinal cohort study including 45 service members with mild blast TBI within 7 days of injury (mean 4 days) and 45 combat deployed nonconcussed controls was carried out. Enrollment occurred in Afghanistan at the point of injury with evaluation of 5-year outcome in the United States. The enrollment occurred from March to September 2012 with 5-year follow up completed from April 2017 to May 2018. Data analysis was completed from June to July 2018. Exposures: Concussive blast TBI. All patients were treated in theater, and none required medical evacuation. Main Outcomes and Measures: Clinical measures collected in theater included measures for concussion symptoms, posttraumatic stress disorder (PTSD) symptoms, depression symptoms, balance performance, combat exposure intensity, cognitive performance, and demographics. Five-year outcome evaluation included measures for global disability, neurobehavioral impairment, PTSD symptoms, depression symptoms, and 10 domains of cognitive function. Forward selection multivariate regression was used to determine predictors of 5-year outcome for global disability, neurobehavior impairment, PTSD, and cognitive function. Results: Nonmedically evacuated patients with concussive blast injury (n = 45; 44 men, mean [SD] age, 31 [5] years) fared poorly at 5-year follow-up compared with combat-deployed controls (n = 45; 35 men; mean [SD] age, 34 [7] years) on global disability, neurobehavioral impairment, and psychiatric symptoms, whereas cognitive changes were unremarkable. Acute predictors of 5-year outcome consistently identified TBI diagnosis with contribution from acute concussion and mental health symptoms and select measures of cognitive performance depending on the model for 5-year global disability (area under the curve following bootstrap validation [AUCBV] = 0.79), neurobehavioral impairment (correlation following bootstrap validation [RBV] = 0.60), PTSD severity (RBV = 0.36), or cognitive performance (RBV = 0.34). Conclusions and Relevance: Service members with concussive blast injuries fared poorly at 5-year outcome. The results support a more focused acute screening of mental health following TBI diagnosis as strong indicators of poor long-term outcome. This extends prior work examining outcome in patients with concussive blast injury to the larger nonmedically evacuated population

Efficiency Strategies for Facilitating Computerized Clinical Documentation in Ambulatory Care

Most providers have experienced increased documentation demands with the use of electronic health records (EHRs). We sought to identify efficiency strategies that providers use to complete clinical documentation tasks in ambulatory care. Two observers performed ethnographic observations and interviews with 22 ambulatory care providers in a U.S. Veterans Affairs Medical Center. Observation notes and interview transcripts were coded for recurrent strategies relating to completion of the EHR progress notes. Findings included: the use of paper artifacts for handwritten notations; electronic templates for automation of certain parts of the note; use of shorthand and phrases rather than narrative writing; copying and pasting from previous EHR notes; directly entering information into the EHR note during the patient encounter; reliance on memory; and pre-populating an EHR note prior to seeing the patient. We discuss the findings in the context of distributed cognition to understand how clinical information is propagated and represented toward completion of a progress note. The study findings have important implications for improving and streamlining clinical documentation related to human factors workload management strategies

Microarray detection of human parainfluenzavirus 4 infection associated with respiratory failure in an immunocompetent adult.

A pan-viral DNA microarray, the Virochip (University of California, San Francisco), was used to detect human parainfluenzavirus 4 (HPIV-4) infection in an immunocompetent adult presenting with a life-threatening acute respiratory illness. The virus was identified in an endotracheal aspirate specimen, and the microarray results were confirmed by specific polymerase chain reaction and serological analysis for HPIV-4. Conventional clinical laboratory testing using an extensive panel of microbiological tests failed to yield a diagnosis. This case suggests that the potential severity of disease caused by HPIV-4 in adults may be greater than previously appreciated and illustrates the clinical utility of a microarray for broad-based viral pathogen screening

Integrating Biological and Social Processes in Relation to Early-Onset Persistent Aggression in Boys and Girls

This study examined the relationship between biological and social risk factors and aggressive behavior patterns in an Australian high-risk sample of 370 adolescents. Perinatal, temperamental, familial, sociodemographic, and behavioral data were collected during interviews completed during pregnancy, immediately postpartum, and when the children were 6 months old and 5, 14, and 15 years old. Youths were given tests of verbal and neuropsychological functioning at the age 5 and age 15 follow-ups. Youths were divided into early-onset persistent aggression, adolescent-onset aggression, and nonaggressive behavior groups. Results revealed that the interaction of biological and social risk factors was significantly related to early-onset persistent aggression. Gender and developmental phase of measurement moderated the relationship between biosocial risks and the outcomes of early-onset persistent aggression and adolescent-onset aggression

Development Status of High-Thrust Density Electrostatic Engines

Ion thruster technology offers the highest performance and efficiency of any mature electric propulsion thruster. It has by far the highest demonstrated total impulse of any technology option, demonstrated at input power levels appropriate for primary propulsion. It has also been successfully implemented for primary propulsion in both geocentric and heliocentric environments, with excellent ground/in-space correlation of both its performance and life. Based on these attributes there is compelling reasoning to continue the development of this technology: it is a leading candidate for high power applications; and it provides risk reduction for as-yet unproven alternatives. As such it is important that the operational limitations of ion thruster technology be critically examined and in particular for its application to primary propulsion its capabilities relative to thrust the density and thrust-to-power ratio be understood. This publication briefly addresses some of the considerations relative to achieving high thrust density and maximizing thrust-to-power ratio with ion thruster technology, and discusses the status of development work in this area being executed under a collaborative effort among NASA Glenn Research Center, the Aerospace Corporation, and the University of Michigan

High Thrust-to-Power Annular Engine Technology

Gridded ion engines have the highest efficiency and total impulse of any mature electric propulsion technology, and have been successfully implemented for primary propulsion in both geocentric and heliocentric environments with excellent ground/in-space correlation of performance. However, they have not been optimized to maximize thrust-to-power, an important parameter for Earth orbit transfer applications. This publication discusses technology development work intended to maximize this parameter. These activities include investigating the capabilities of a non-conventional design approach, the annular engine, which has the potential of exceeding the thrust-to-power of other EP technologies. This publication discusses the status of this work, including the fabrication and initial tests of a large-area annular engine. This work is being conducted in collaboration among NASA Glenn Research Center, The Aerospace Corporation, and the University of Michigan

TEACHER MOBILIZATION: A CASE STUDY ON ORGANIZATIONAL FACTORS & THE MOVEMENT OF TEACHERS WITHIN AN URBAN DISTRICT

Professional educators are known to have one of the highest attrition rates among the American professions. As a result, administrative personal face financial hardships in the effort to attract, develop, and often replace large numbers of educators on a yearly basis. The National Center for Educational Statistics (NCES), in a 2016 report, found that over 15% of the national education workforce either left or mobilized within the profession between 2011 and 2013. Another report from the Alliance for Excellent Education in 2014 indicated that school and district administrators spend on average 2.2 billion dollars annually to replace teachers. These expenses account for both attrition (48.7%) and mobilization (51.3%). This dissertation was conducted in an urban school district with a high enrollment of high-poverty minority students. For this study, nine teachers were chosen from the K-12 grade levels with varying teaching experience. This case study examined the perceptions of full-time teachers who left one school yet remained teaching within the same district. Using organizational theory based on Maslow’s Hierarchy of Needs, the perceptions of teachers were explored in order to identify the possible factors that contributed to their decision to leave. A case study was necessary to determine why the decision to leave was made, given the specific context of the organization. Data was collected through surveys, interviews, and artifact collection. The interview protocol presented the interview process, the questions, and notes related to the interview experience (Creswell, 2002). Personal notes and digital voice recorders were used to capture participant testimony. Data analysis included a six-step process developed by Braun, Clark, and Terry (2012) to capture and code the data. Qualitative data analysis software, NVivo, was used to maintain a chain of evidence that recognized emergent themes from participant testimony. The key themes that emerged from the data were (a) perceived leadership support, (b) standardized testing pressures, and (c) quality and meaningful parental involvement. The findings aligned with current and historical research that the absence of teacher support, stressors related to standardized testing, and feelings of isolation contributed to teacher dissatisfaction

God and reason: An intellectual religious journey through the mind of Thomas Paine

Thomas Paine was one of the most prolific writers in the Age of Revolutions. His writings can be analyzed from a political, philosophical, humanitarian, or religious point of view. However, it was Paine\u27s use of religious rhetoric that ultimately led to the demise of his character and reputation as a popular actor in the American Revolution. Most historiography on Paine focuses in on one of the mentioned perspectives, leaving out a much larger narrative or arch of Paine\u27s life. This thesis will cover a series of Paine\u27s writings beginning with his first, The Case of the Officers of Excise (1772), written in England before his arrival to the colonies and end with, Age of Reason (1794), written in France during the revolution. This thesis will also show how Paine\u27s use of religious rhetoric changed over time, with the hope of giving more insight to Paine\u27s thoughts. Paine\u27s diary was his writings and the only way to examine Paine is by examining his writings and correspondences. To help accomplish this, an array of primary sources is used in this thesis, along with recent historiography where Paine makes appearances. By piecing these sources together, a much larger narrative on Paine and his religious thinking can be told
